To all whom t may concern.'

Be it known that I, NICHOLAS WEILEB, Of Fort Collins, in the county of Larimer and State of Colorado, have invented certain new and useful Improvements in Disk rdrang-Flows, which improvements are de'- scribed in the following specification and are illustrated by the accompanying drawings.

The invention relates to gang plows of that kind in which several gangs of plow disks lare united in a single plow, drawn by atraction engine or motor.

,The objects of the Ainvention are to lift the disks of such a plow out-of the ground at the end of the field without raising the gang frames; and to hold them clear of the ground, when not in use; to raise and lower the plowI disks, relatively to the gang frames by which they are carried; to raise and lower the gang frames in a superior manner; to arrange the plow gangs, when not in use, to track in a straight line behind the engine; to lock the plow disks automatically in position, when lowered into theground; to engage successive gangs with each other in a special manner; to guide each of the gangs of such a plow automatically to its proper position, relative to the plowed ground, and hold it there, while at work; and in general-to produce a superior plow of the kind above specified. In accomplishing these objects I provide the plow gangs with rudders, which are adapted to run in the plowed ground, and attach the plow disks to the gang frames by -means of pivoted brackets.

The best manner in which I have contemplated applying the principles of the invention, is illustrated by said drawings; in which- Figure 1 is a plan of a disk gang plow, which is constructed in accordance with these principles, and shown in working position. Fig. 2 is .a like view ofthe draft mechanism of the same plow, on a reduced scale. F ig. 3 is an enlarged plan of a portion of a like plow in a like position- Fig. 4

is aside elevation of Fig. 3. Figs. 5 to 9 inelusive are enlarged details. Fig. 10 is a detail perspective view ofthe front half of one gang and the rear half of its preceding gang, parts being broken away to show con.- struction.y Fig. 11 is a detail' transverse `section across the center of a gang.

yof its respective branch of. the-bent'bar 4 of In Figs. 1, 3 and 4, the several gangs are designated generally, in their order from front to rear of the plow, by the numerals 1,l 2 and 3 respectively. 'In general features these gangs are of a single type andthe description of any applicable to each of the othersf The frame of eachfgang comprises a horizontal bent bar, having a middle straight port-ion L1. The frame of the rear gang 3 has a forward lateral branch 5 and two di vergent rear branches 6 and 7 The forward lateral branches 5 ofthe intermediate gangs Patented Mar. 4, iai.

one gang willbe equally may be integral or 'bolted to the respective f brackets 17 hereinafter described and arefse- `cured to the straight portions 4; which carry also comprises a horizontal bent bar 9,

which is united with bar 4 by bolts and by cross braces 10. The rear frame rides onv three wheels 11, 12 and 13, and the'otherv frames -upon the two wheels. 11 land 12,

which wheels supportthe free ends of said i branches respectively, by means .of hinged connections, consisting 1n each instance o-f a bent rod or axle 14,v having a vertical arm 15, fitted withA a loose sleeve cap, 16, which is provided with an external screw thread cal bracket 17, rigidly mounted upon the end the same gang beam.' Bya bend inthe axles of said left wheels 12, the latter are caused to trail. always' behind their brackets 17;:

while the right wheels.y 11. arecaused'- to `run uniformly in the desired direction vbymeans and works in an internally threaded vertiv:ioo A of draft rods, 18, which are pi-voted tothe f gang frames respectively, and are connected with they axles of those wheelsl by links '33 z' and levers l32. The lateral swing of thesey draft rods 18 is limited bye-*stops ,34. on

branches 6 of the gang frame, and by ver?" tical stop pins 55, which are removably inserted through stops 34. These pins maya@ .the same time be inseited through "cynical holes in bars-18, whenever it is desired to fasten those bars in their extreme posit-ions Atoward the right, shown in Fig. 3.

To the described gang frame are attached at suitable intervals a suitable number of plow disks 19. The mannerL of this attachment is shown in detail in Figs. 5 and 6, which are an elevation and a plan respectively of portions of the gang, including one of these disks. This disk, being of any ordinary or proper form, is rotatably mounted on a bracket 21, which is pivoted to the side of the main beam, that is to say, to the angle-iron 8, by pin 22. Being mounted in this manner, the disk can be lowered to the full-line position shown in Figs. l, 34, 5 and 6, or raised to the position shown in do-tted lines in Fig. 5, or even to a higherposition, by a pivotal movement of this bracket, as occasion may require. For the purpose of raising and lowering this bracket, as described, the latter is provided with a lug 23, to which may be attached a link 35.

To the plow gang, and preferably to the.

frame of the gang, a guide or rudder is similarly attached, consisting preferably of a rotary disk 20, which is shown in connection with gang 2 in Figs. 1, 3 and 4, and in detail in Figs. 7, 8 and 9. Fig. 7 is a plan of a portion of the gang, including rudder 20, while Figs. 8 and 9 are elevations of Fig. 7. In an alternative form thisrudder may be angular, as shown in connection with gang 3 in Figs. l and 3. Rudder 2O is provided with a bent axle, having a vertical portion 24, having a fixed collar 25. The vertical portion of thisaxle is rotatablein a sleeve bracket 26, which is fas ened to angle-iron 8 by a bolt or pin 27. lif ing bar 28 is pivoted to bracket 26 by the s1ne pin 27, and is connected with collar 25 by link 29; and to the end of this bar 28C?v is attached a link 30. For the purpose of ing direction to the rudder, the same is connected with the draft-bar18 in a parallel motion, consisting of a rigid horizontal lever arm 3l on axle 24, an arm 32 of said draft-bar, and a link 33, connecting said arms. For the purpose of raising the plow disks and the rudders out of the ground, thebefore-mentioned links 30 and 35 are attached to a horizontal reciprocable bar, preferably of angle-iron, 36. This bar is supported on rollers 37, and is held in positio-n thereon by screws 38, which work in slots 39 of said bar, and take into brackets 40 on the gang frame, partI 8. The saine bar is also provided with a rack 41, engaged by a pinion 42, which is mounted on the gang frame, part 8, and is operated by the lever handle 43; This handle may be held in the position shown or in the reversed position by stops or catches 56.

The reciprocable bars 36 of the several gangs may be impelled forward in unison givby connection with the` piston-rod 44 of a steam cylinder 4.5, which is mounted on gang l and is supplied with steam from the boiler of the traction engine thro-ugh a ilexible steam pipe 46. This connection is made by fastening the piston rod 44 to a bracket 47 on the reciprocating bar 36 of gang 1 and by connecting the successive reciprocating bars of the different gangs with each other by chains 48.

Each of the gangs 2 and 3 engages the gang before it by means of a horizontal supporting bar 49, whose forward .end is bolted to the beam of the preceding gang inthe position shown, and whose rear end portion plays loosely in a horizontal slot through the arm or branch 5 ofthe follow.

ing gang.

The draft. mechanism, which is shown in Figs. 1 and 2, comprises a draw-bar 50, which is pivoted to the middle of a cross-bar 51, a grooved pulley 52, which is carried by this cross-bar, a chain 53, which is attached to the end portions of this cross-bar and runs over saidpulley, together with cables 54, which are attached to draft rods 18 of each of the gangs, respectively, and to said cross-bar.

Such being the construction of my iinproved gang plow, its operation accomplishes all of the above-mentioned objects of the invention.

By turning with a wrench the screw cap 16 in post 17, the operator raises or lowers the gang frames as may be required. The described lever handles, being turned to a horizontal position in either direction, and acting through wheel 42, rack 41, reciprocating bar 36, links and pivoted brackets 21, raise and lower the disks ofeach gang as may be desired, without raising or loweringl the gang frames. The steam cylinder, with its contained piston, being operated from the engine, and acting through bars 3G, chairis 48,links 35 and brackets 21, similarly raises alli said disks simultaneously, when necessary. The disks when lowered into the ground, are locked in position, being held down by links as shown in Fig. 5. The disks are held up, clear of the ground, when not in use, by catching the lever handles 43 horizontally back. The gangs are guided to their proper positions, and held there, by the rudders 20, which run partly in the ground, as shown in Figs. 8 and 9. i in turn are directed by the engine through draft rods 18, 18, 18, acting upon the pivoted rudder arm o-r axle 24 by arms 3l and 32 and links 33; and are raised and lowered in unison with the plow disks, by the same movements of the reciprocable bars 36, acting through mechanism shown in Figs. 7, 8 and 9. The gangs are arranged to track in line behind the engine in traveling by uncoupling the engine from the draw-bar These rudders,

Louwes 50, by coupling the same to the draft rod 18 of gang 1, by uncoupling the cablesv 54 from all the draft rods, by swinging by hand the draft rods ofgangs 2 and 3 to the extreme right, as shown in dotted lines in Fig. 3,' "and by fastening 'said rods in that position by stop pins 55.

The special engagement of successive gangs by bar49 not only-brings a part of the-weight of the preceding gang upon its successor, but prevents those two gangs from getting out o proper alinement with each other.' At the same time the rudders not only guide the .gangs but also serve .as landsides, resisting. the etlort of the gangs 'to crowd away from the plowed ground.`

Such beingthe construction and operation of my invention, I claim 1. A plow gang, comprising a gang frame; disk-carrying brackets, which are attached to said frame `by pivots; a lreciprocable bar, which is attached to said brackets yby links; a rack andf'pinion, which are bar, which is mounted on said frame, and
